WIRE STRETCHING AND TWISTING TOOL.

SPECIFICATION forming part of ALetters Patent No. 491,111, datedFebruary "i, 1893.

Application led May 27,1892. Serial Nol 434,692. (Model.)

To @ZZ whom. t may concern.-

Be it known that I, ELI T. HOYT, a citizen of the United States,residing at Algansee, in the county of Branch and State of Michigan,have invented a new and useful Wire Stretching and Twisting Tool, ofwhich the following is a specification.

My invention relatesto improvements in wire stretching and twistingtools; and its object is to provide a device for this purpose which willdraw two ends of the wire together, thus stretching the wire, aud thentwist the ends tightly together.

In my drawings,in which similar letters refer to similar parts, Figure lgives a prospective view of my device, and Fig. 2 shows a cross sectionthrough the twisting head at right angles to the length of the tool.

My device consists primarily of two similar parts A, which may be flaton' the sides adjacent to each other and are pivoted together by anutted bolt g passing through the disklike heads h on the lower oroperating end of these parts. The outsides of these disks may be more orless rounded or convexed. Also pivoted on the bolt g, outside of eachofthe disks h, are two locking pieces a, one near each end of the bolt andheld in tension against the disk by screwing up the nut in thescrewthreaded end b of the bolt. These locking pieces are made with oneend projecting to nearly the circumference of the disk and undercut onthe side toward the disk and as far back as desired from the end. Thus aprojecting finger is formed between which and the disk is sufcient spacefor the wire zu to be operated upon, which Wire is thus held in placeunder more or less frictional tension. From these disks h, extendhandles 4o f, by which the device is operated and these I handles may beshaped or out away as desired. Near one edge of each of these disks at apoint nearly opposite the handle projects a lug c', slightly undercut atthe outer edge so as to form a groove e between it and the edge of thedisk for the passage of the wire. These grooves c are oppositelyarranged and are substantially in parallel planes, each groove beingpreferably at a slight angle with the plane of the disks. These groovesserve as guides for the wires while being stretched and twisted. At oneside of this lug, andl also near the edge of the disk, a pin c extendsat substantially right angles to the plane of the disk and handle. Thesepins are so arranged that when the handles are together one pin is onone side, and the other on the other, of the axial line through thedevice, as seen in Fig.'2. Or the Vlugo' and pin c may be closertogether or even merged together, and the groove may extend from underthe lug to and around the pin. The part A,/with its handle, disk, lug,and pin,is preferably all of one piece of cast iron; but it mayobviously be made of other inaterials, as desired, and the pieces f, h,i, and c may be rigidly connected or fastened together.

The operation of the device may be readily understood from the foregoingdescription, taken in connection with Fig. 1, which shows one of itsuses. In thisvflgure the wire w is seen passing about some object P tobe wired, and the free ends dof the wire, which overlap or cross eachother and extend in opposite directions, are passed along the grooves cunder the lugs i, and around the pins c. The free ends d are then loopedback, to allow the more ready doing of which the fingers of the lockingpieces a may be swung back or away from the pins c, and after loopingthe wire about the pins the fingers of the locking pieces are swung overthese ends of the wire, and the locking pieces may then be tightly heldin this position by screwing up the nut on the bolt g. When this isdone, or before if desired, the disks are rotated on the bolt g by meansof the handles, thus stretching the ends of the wire by each other andtightening it; after which the ends of the wire are twisted tightlytogether, as shown, by giving to the device a screw-driver or augermotion. By reversing therotation of the disks, further slack may begained in the wire, which may then be taken up by further twisting.'

The tool may evidently be used in tightening and twisting the ends ofwire about a fence picket o r post, in taking up slack in a fence wire,or in tightening wire about a bale or bundle, and for several otheranalogous purposes.

What I claim is- A tool for stretching and twisting wires,

IOO

which consists of two disks having a lug on In testimony whereof I affixmysignature in presence of two Witnesses.'
